Problems solved by technology

[0002] There are currently three types of recarburizers available in the market: one is petroleum coke that is directly used as a recarburizer after calcination, the disadvantage is that it is of low grade and belongs to high-sulfur, high-nitrogen, high-ash low-grade recarburizer; the other is grap...

Embodiment Construction

[0012] The embodiment of the present invention is shown in accompanying drawing, utilizes the Acheson furnace equipment to carry out production, and the bottom of the furnace is paved with thermal insulation material 8 at a distance of 400 mm from the bottom of the lower conductive electrode 7, and the furnace type plate 4 is used to encircle a rectangular furnace type, and the second layer is paved in the furnace. A layer of petroleum coke 5, the first layer is paved to the bottom of the lower conductive electrode 7 of the furnace head and tail in the furnace, and then compacted, and then the second layer is laid corresponding to the conductive electrodes 7 of the furnace head 1 and the furnace tail 9 of the Acheson furnace. A layer of baked carbon material is used as the conductive heating core 6, and there are three conductive heating cores in the lower layer, each of which is connected by 7 pieces of 1.8-meter-long carbon material baked products. When the length is not suita...

Abstract

This invention relates to a technique for manufacturing graphitized petrol coke in an Acheson type graphitization furnace, which comprises: hierarchically distributing petrol coke in the graphitization furnace, placing carbon material baking product between the electrodes at both ends of the furnace as electrically conductive heating elements, and using insulating materials composed of coke powders and quartz sands to fill the surroundings of the furnace. The electrically conductive heating elements can heat the petrol coke using the direct electricity provided by the rectification switchgear so that the temperature of the petrol coke reaches 2200-2500 deg.C, and the petrol coke is thus graphitized into recarburizing agent, which has such advantages as high quality, low sulfur, nitrogen and ash content, and excellent physicochemical index.

Description

technical field [0001] The invention relates to a process for producing graphitized petroleum coke by an Acheson graphitization furnace. technical background [0002] There are currently three types of recarburizers available in the market: one is petroleum coke that is directly used as a recarburizer after calcination, the disadvantage is that it is of low grade and belongs to high-sulfur, high-nitrogen, high-ash low-grade recarburizer; the other is graphite electrode The leftovers produced by machining can also be used as recarburizers. The disadvantage is that the market supply is small and the quality is extremely unstable; the first is a by-product in the production of other graphite products, and the disadvantage is that it cannot be mass-produced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a process for producing a high-grade, excellent physical and chemical index, low-sulfur, low-nitrogen, and low-as...
